The first clinical trial comparing a hemostatic patch (Tachosil ®) versus the standard surgical hemostasis with Argon was published by Frilling et al in 2005 (Frilling et al Langenbecks Arch Surg. 2005). It was observed a reduction in the intraoperative time for hemostasis and less posterior drain in the Tachosil ® group (N = 121).
